Is grout for masonry required to consist of cementitious material and aggregate?

  1. True

  2. False

The correct answer is: True

Grout for masonry is indeed required to consist of cementitious material and aggregate. This requirement is essential because grout serves the purpose of filling voids in masonry units, providing structural integrity, and enhancing load-bearing strength. The combination of cementitious material, typically Portland cement, and aggregate creates a robust mixture that can adequately bond with masonry units, ensuring durability and stability in construction. The use of cementitious materials provides the necessary binding properties, while aggregates help improve the strength and reduce shrinkage. This blend is critical for performance and longevity in masonry applications. Therefore, the affirmation that grout must include both components aligns with construction standards and best practices in masonry work.
